Logitech Attack 3 Joystick communication

Hi,
I have two Logitech Attack 3 joysticks and a number of Arduino Nano's. I have these working together to control an RC hydraulic excavator but I hacked into the joystick and use the analog signals.

I saw on the forum others have managed to use the joystick connected to the computer over USB and communicate with arduino.

What I want to do is interface the joystick directly to a Nano/Arduino without needing the computer in the setup so i can use the joystick control remotely. Is there a library or existing sketches that might help just translate the serial communication to the arduino?
